I simulated DPPC60%-DMPC40%+protein bilayer system for 100 ns. Now I want to run another simulation for 50 ns on this system. I wonder if its nessecery to use .cpt file from the previous md run.
I want to know what the difference is between using and not using .cpt file. here is the command line to run grompp:
grompp -f md.mdp -c md.gro -t md.cpt -p topol.top -o md2.tpr
what if I use this command line :
grompp -f md.mdp -c md.gro -p topol.top -o md2.tpr.
whats the differences?
